A 64-pitch worm gear with 60 teeth, a 0.2498 in. bore, and a single-threaded worm, designed for use with a 14-1/2° pressure angle system. The gear is made from bronze QQ-B-637 alloy 464 and pairs with a 303 stainless steel worm. The gear has a 60:1 ratio and is pitched for inch-based components, with a hub fit for a 7/64 in. screw and a 0.312 in. shaft diameter. Available bore sizes are specified as 0.1248 in., 0.1873 in., and 0.2498 in., with this variant using the 0.2498 in. bore. The worm gear supports single, double, or quadruple thread worm drivers, this part engaging with a single-threaded worm. The gear is sized for a pitch diameter of 0.9375 in. and an outside diameter of 1.0156 in.
A worm gear pair, or worm gear set, consists of two gears: the worm, which resembles a spiral screw, and the worm gear (aka, worm wheel).
For the pair to mesh, the worm and worm gear must have the same pressure angles, modules, and lead directions (left- or right-hand).
A worm revolves on a shaft that’s perpendicular to the worm gear and the shaft angle is typically 90°. Because the teeth gradually mesh as the worm rotates, there is low noise and low vibration.
